The following topics describe how to view information about the cluster, nodes, and brokers using the Central Management Web UI and the Virtual Execution CLI.

Prerequisites

  • Monitor, Operator, or Admin access

Viewing node status using the Central Management Web UI

Use the Appliances > Nodes page in the Central Management Web UI to view a list of the nodes this Central Management appliance manages and their overall status. You can then click a node name for more detail.

The following table shows the node status fields.

To view node status:
  1. Log in to the Central Management Web UI.

  2. Select Appliances > Nodes.

  3. Click the node name in the Name column to view additional details.

Viewing node status using the Virtual Execution CLI

Use the commands in this section to view the status of brokers and compute nodes in an IVX cluster.

To view node status:
  1. Log in to the Virtual Execution CLI.

  2. Enable the CLI enable mode:

    vx-hostname > enable
  3. To view the node status:

    vx-hostname # show mvx node status
  4. To view detailed status information:

    vx-hostname # show mvx node status full
